Abstract
Abstract An upper component lens which refracts a convergent conical incipient beam of diffused sunlight, forming an annular beam and a convergent conical beam; a middle component lens which refracts the annular and convergent conical beams, forming a convergent conical beam; and a lower component lens which refracts the convergent conical beam, forming a concentrated whole beam.

Independent Claim
216 words
A conical beam concentrator comprising in general three component lenses which receive a convergent conical incipient beam of diffused sunlight and emit a concentrated circular whole beam parallel to the optic axis of the lenses, and comprising in particular; an upper component lens RT (1) having a convex conical section (6) which receives and transmits a convergent conical incipient beam (5) of diffused sunlight, and having a concave conical section (7) which refracts incipient beam (5), forming annular beam (9), and having a planar section (8) which refracts incipient beam (5), forming convergent conical beam (10), a middle component lens RT (2) mounted below upper component lens RT (1) and having a planar section (11) which transmits annular beam (9), having a convex conical section (12) which transmits convergent conical beam (10), having a convex conical section (14) which refracts annular beam (9) and a concave conical section (13) which refracts convergent conical beam (10), forming convergent conical beam (15), and a lower component lens RT (3) mounted below middle component lens RT (2) and having a convex conical section (16) which transmits convergent conical beam (15), and having a concave conical section (17) which refracts convergent conical beam (15), forming concentrated whole beam (18) which is emitted parallel to the optic axis of the concentrator.
